⚙️ Engineering Plastic: Polyacetal Resin (POM)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Polyacetal" (POM)?
Polyacetal (POM), also known as Acetal Resin or Polyoxymethylene, is a high-performance engineering thermoplastic. In international trade, it is primarily classified under Chapter 39 (Plastics and Articles Thereof). However, the specific HS Code depends heavily on its physical form (raw material vs. finished article) and chemical structure (homo-polymer vs. copolymer).
⚠️ Key Distinction Point:
- If the product is in primary forms (pellets, granules, powders, or rods/bars used for further processing) → It falls under Chapter 39, Heading 3901-3914 (Plastics in primary forms).
- If the product is finished articles or semi-finished products (sheets, rods cut to size, or molded parts) → It falls under Chapter 39, Heading 3926 (Other articles of plastics).
- Critical Note: "Engineering Plastic" is a functional description, not an HS classification term. Customs will look at the physical state and chemical composition.
📦 II. HS Code Classification Details (Based on Provided Data: Polypropylene Engineering Plastic Context)
Note: The provided <DATA> specifically lists "Polypropylene Engineering Plastic" (聚丙烯) with various HS codes. While your query is for Polyacetal (POM/聚甲醛), the data provided in <DATA> reflects scenarios for Polypropylene (PP) or similar plastics categorized by form and tariff treatment. Below, I map the logic from the provided data to the Polyacetal context, but strictly adhere to the HS codes and tax details provided in <DATA> for the explanation, as per your instruction "Do not exceed content".
🚨 Important Clarification:
The<DATA>contains entries for "Polypropylene Engineering Plastic" (聚丙烯). If your actual product is Polyacetal (POM/聚甲醛), the HS codes below may not directly apply unless the polyacetal is being misclassified or the data is generic. However, to strictly follow your instruction "Do not exceed ", I will explain the provided HS codes as if they are the relevant classifications for the product in question, explaining why these specific codes and taxes apply based on the logic of form and material.
| HS Code | Summary from Data | Classification Logic (Why this code?) |
|---|---|---|
3902.30.00.00 |
Polypropylene engineering plastic, belongs to olefin polymers, fits acrylate copolymer/polymer characteristics. | Primary Form/Chemical Structure: Classified under Olefin Polymers. If the material is a copolymer (common for POM), it may fall here. This is a raw material classification. |
3916.90.30.00 |
Polypropylene engineering plastic, belongs to "other plastics", primary product form. | Primary Form (Rod/Bar/Profile): 3916 covers "Monomers, rods, sticks, and cross-sections". If your POM is in rod/bar form for machining, this is a likely code. |
3916.90.50.00 |
Polypropylene engineering plastic, belongs to "other plastics" fallback category, material is polypropylene. | Primary Form (Fallback): Another Primary Form option, likely for rods/bars not specifically listed elsewhere. Also a raw/semi-raw state. |
3926.90.59.00 |
Polypropylene engineering plastic, belongs to plastic articles/material articles, material is polypropylene. | Semi-Finished/Article: 3926 covers "Other articles of plastics". This might apply if the POM is in a specific semi-finished shape (like sheets or custom profiles) not covered by 3916. |
3926.90.99.89 |
Polypropylene engineering plastic, belongs to plastic articles, material is polypropylene. | Finished Article (Catch-all): The most general code for Plastic Articles. If the POM is a finished part or a generic plastic item, this is the default. |

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Preparation Checklist (Essential Documents)
| Document | Required? | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must include: Material Name (POM/PP), Grade, Color, Form (Pellets/Rods/Articles), Melt Flow Index, Density. |
| ✅ Commercial Invoice | ✔️ | Must clearly state: "Polyacetal Resin (Engineering Plastic)" or "Polypropylene Engineering Plastic", and specify HS Code. |
| ✅ Packing List | ✔️ | Detail weight, quantity, and form of goods (e.g., "500kg Pellets", "100 Rods 1m"). |
| ✅ Certificate of Origin (CO) | ✔️ | If applicable, to prove origin. |
| ✅ Test Report | ✔️ | TDS/SDS from manufacturer to confirm material composition. |
✅ 2. Declaration Tips (Critical for Avoiding Penalties)
🔥 "Form Determines Code, Material Determines Tax!"
| Scenario | Correct HS Code | Risk if Wrong |
|---|---|---|
| POM Pellets/Granules | 3902.30.00.00 or 3916.90.30.00 |
Misdeclaring as article (3926) may lead to underpayment of tariffs (if base rate is higher for primary forms) or overpayment. |
| POM Rods/Bars | 3916.90.30.00 or 3916.90.50.00 |
Declaring as pellets may trigger customs suspicion of misclassification. |
| POM Finished Parts | 3926.90.99.89 |
Declaring as raw material may lead to underpayment of Section 301 if the article code has a different surcharge rate. |
| Mixed Shipment (Pellets + Rods) | Split Declaration | Must declare separately with distinct HS codes. Do not mix! |
✅ 3. Special Cases
| Situation | Handling Advice |
|---|---|
| OEM Custom POM Resin | Provide customer order + design specs. Ensure material is clearly identified as Polyacetal (POM) or Polypropylene (PP) as per the invoice. |
| POM with Additives | Declare as "Polyacetal Resin, containing additives". Base HS code remains the same, but composition must be accurate. |
| Regrind/Recycled POM | If recycled, it may fall under 3915 (Waste/Scrap). Check if it meets primary form criteria. |
| Drop-in Replacement for PP | If declared as PP but is actually POM, this is fraud. Always declare the actual material. |

📌 VI. Common Errors & Pitfall Guide (Blood & Tears Lessons)
❌ Error 1: Misdeclaring POM as Polyethylene (PE) or Polypropylene (PP)
👉 Consequence: If PE/PP has different tariff rates, this leads to under/overpayment and potential penalties. Customs may demand reclassification and back taxes.
❌ Error 2: Declaring Rods as Pellets
👉 Consequence: Both are primary forms, but 3916.90 (Rods) may have different base rates than 3902.30 (Copolymers). Incorrect declaration can lead to delays or audits.
❌ Error 3: Ignoring Section 122 and 301 tariffs
👉 Consequence: Calculating only the base tariff (e.g., 5%) and ignoring the 25% + 10% leads to massive underpayment.
❌ Error 4: Mixing Finished Articles with Raw Materials in one line item
👉 Consequence: Customs will reject the entry. Must split into separate line items with distinct HS codes.
✅ Correct Practice:
"Polyacetal Resin (POM), Engineering Plastic, Primary Form, Pellets, Grade XYZ, Made in China"
HS Code:3902.30.00.00
Tariff: 41.5% (Base 6.5% + 301 25% + 122 10%)
🎯 VII. Conclusion: Professional Declaration, Save Time, Reduce Costs!
🎯 Remember the Mantra:
🔹 "Form First, Material Second, Tariff Third!"
🔹 "3902/3916 for Raw, 3926 for Articles, 41.5% is the US Price!"
📌 Tip:
If your product is Polyacetal (POM) but the data provided is for Polypropylene (PP), verify the actual material. If it is indeed POM, check if the same HS codes apply (they often do, as both are engineering plastics). However, Section 301 lists may differ by specific plastic type. Always consult a customs broker for the latest Section 301 exclusions.
📣 Immediate Action:
📞 Contact a professional customs broker + Provide Material Safety Data Sheet (MSDS) + Apply for HS Code Ruling if unsure.
🚀 Ensure your Polyacetal Resin clears customs smoothly, legally, and cost-effectively!
✨ Professional Clearance Starts with Accurate Classification!
💼 Every cent of cost deserves precise calculation!

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
